SEECIFICATION forming part of Letters Patent No. 719,100, dated January 27, 1903.

Application filed July 5,1902. Serial No. 114,394. (No model.)

To (LZZ whom, it may concern:

Be it known that I, HYACINTHE FoIsY, a citizen of the United States, and a resident of Lynn, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Machines for SofteningHides or Skins, of which the following is a specification.

This invention relates to improvements in machines for softening hides or skins, generally termed staking-1nachines,and itis carried out as follows, reference being had to the accompanying drawings, wherein- Figure 1 is a side elevation of the machine, showing a portion of the frame removed for the better illustration of the working parts of the machine. Fig. 2 is a front elevation of Fig. 1. Fig. 3 is a longitudinal section on the line 3 3 in Fig. 2, showing the roller-oarrying arm in position during its backward motion and showing one of the staking-tools in contact with the roller on the roller-carrying arm. partly shown in section, on the line 4 4 shown in Fig. 3; and Fig. 5 is a detail sectional view showing one of the staking-tools moved inwardly out of contact with the roller on the roller-carrying arm to permit the said roller to move forward free of the staking-tool, as will hereinafter be more fully described.

In the drawings, A A represent the sides of the frame of the machine secured at proper distances apart by means of stays or braces, as usual.

B is the driving-shaft, journaled in bearings in the frames A A and set in a rotary motion by belt-power applied to a pulley C on said shaft or in any well-known or suitable manner. On the shaft B is secured a crank D, to which is pivotally connected a rod or link E, the other end of which is pivotally connected to an arm F, which is looselyjournaled on a shaft Gr, journaled'in bearings in the frames A A in any suitable manner.

Preferably integral with the arm F is made an arm F, to which is secured a segmental arm F, in hearings in the forward end of which is journaled a spindle h, to which is secured a grooved spreader-roll H, provided with a series of inclined or curved peripheral ribs 7?. 7r, oppositely inclined or curved from Fig. a is a top plan of the machine,

the center outward, as shown in Figs. 2 and 3, which ribs serve to spread out the skin from the middle portion of the roll outward during the staking operation.

To the upper portions of the frames A Ais secured a segmental arm I, to which is suitbly secured a pair of toothed segmental racks M, as shown in Figs. 1, 2, 3, and 5.

To the ends of the spindle h of the grooved spreader-roll H aresecured pinions h h", which engage the teeth of the stationary segmental racks 'L' i, as shown inFig. 1, causing the spreader-roll H to rotate in one direction during the forward motion of the oscillating arm F and in an opposite direction during the backward motion of said oscillating arm F.

'- It will be noticed that an oscillating motion is imparted to the arm F by the rotary shaft B and the crank-arm E during the operation of the machine as above described.

On the shaft G is secured a staking-toolcarrying frame, composed of aseries of radial arms K K, to one side of which issecured a ratchet-wheel or toothed disk L, which is actuated by a spring-pressed pawl f, pivotally connected to the oscillating arm F and adapted to engage the said toothed disk L during the backward motion of the segmental arm F, by which arrangement an intermittent rotary motion is imparted to the staking-toolcarrying frame during the oscillating motion of the segmental arm F, as shown.

In radial guides on the arms K are radially movable the slides M, each one being laterally perforated for the reception of a spindle m, to the ends of which are secured rollers 'm 'm. (Shown in Figs. 1 and 4.)

75 represents radial slots in the arms K to permit a radial movement of the spindles m m during the radial motion of the slides M during the operation of the machine, as will hereinafter be described.

The slides M are automatically moved toward the axis of the shaft Gby the influence of springs N N, connecting one slide to the one diametrically opposite, or in any other suitable or well-known manner, as shown in Figs. 2, 3, and 4. During the rotary motion of the arms K the slides M are intermittently expanded by the slide-rollers mf coming in contact with track-plates O O, secured to a forked lever or arm P, pivoted to the frames atpp, as shown in the drawings. The said track-plates are vertically adjustable for different thicknesses of leather, so as to obtain the desired pressure on the skin, &c., between the staking-tool M, secured to or forming part of the slide M, and the grooved spreader-roll H during the operation of the machine. The staking-tool M is rigidly secured to the outer end of the radially-movable slide M, so as to cause a proper tension against the spreader-roll H and the hide or skin held between them by the action of the rollers m engaging the adjustable tracks 0 0 during the staking operation.

In practice I adjust the position of the track-plates O O by means of a wheel P, secured to a vertical spindle P, the lower end of which is suitably journaled in a bearing or bracket 1), secured to the frame of the machine'and having its upper end screw-threaded, as shown atp in 2, and connected to the outer end of the forked lever P, which is screw-threaded to receive the upperend of the spindle P. By this arrangement the trackplates may be vertically adjustable relative to the rollers m on the slides M as may be desired for the regulation of the position of the staking tools M relative to the grooved spreader-roll H and the skin held between them during the staking operation.

To the rear of staking-tool M, on each of the slides M, is secured a rigid or partiallyyielding metal staking-blade M of the kind used in rotarystaking-machines, as shown in Figs. 3 and 4.

The operation of the machine is as follows: The roller-carrying arm or segment F is set in an oscillating motion by any suitable or well-known mechanism, and during such oscillating motion of said segmental arm its grooved spreader-roll H is rotated intermittently in opposite direction by the engagement of the pinions h h with the stationary segmental toothed racks 't' t, as described. During the oscillating motion of the segmental roller-carrying arm F an intermittent rotary motion is imparted to the stakingtoolcarrying arms K K by the pawl f engaging the teeth of the disk L, that is secured to the shaft G and arms K K, as described.

Q is the skin or hide that is to be staked. This is placed between the grooved spreaderroll H and one of the radially-movable staking-tools M at the time the roll H is at the end of its forward stroke, (shown in Fig. 1,) at which time the staking-tool is held stationary and away from contact with said roll by the influence of its spring or springs N. As the staking-tool-carrying arms are rotated in the direction of the arrow shown in Fig. 1 its rollers m engage the tracks 0 O, causing the staking-tool to be forced radially outward again against the spreader-roll H, so as to hold the hide or skin with proper frictional resistance between the said staking-tool and rotary spreader-roll as long as the rollers m m on the slide M are in contact with the tracks 0 0. During such operation the skin or hide Q is held by the operator with a proper tension, causing the grooved roll H to spread out, soften, and stretch the skin or hide by contact with the staking-tool M and coincidently by the staking-blade M causing the hide or skin to'be kneaded and made soft and pliable. As the staking-tool-carrying arm during its rotation reaches the position shown in Fig. 5 its staking-tool and slide are released from the tracks 0 O and moved inward by the action of the springs N N, causing the hide or skin to be released from the roller H and the staking-tool to allow of its adjustment and so as to allow the spreader-roll H to move forward toward the operator without contacting with the stakingtool between which and the spreader-roll the hide or skin has been held and operated on. The arm F, that carries the spreader-roll, now moves forward to itsinitial position, (shown in Fig. 1,) during which movement the staking-tool-carrying arms remain stationary, and during such time the operator adjusts the skin or hide so as to engage a new portion thereof with the staking'devices,and thereby to gradually soften, spread out, stretch, and smooth the entire portion of the skin or hide.

In practice I may employ a suitable friction or brake device applied to the shaft G or a drum or pulley thereon, like the one arranged on winches or hoisting devices, so as to prevent the arms K K from being moved beyond the place in which they are left by the pawl f on the oscillating arm F and to to be frictionally held in such position until such pawl again engages with the ratchetdisk L on the shaft G. This friction or brake device is, however, not shown in the draw ings, as it is a well-known friction retaining device in machinery of various kinds.

What I wish to secure by Letters Patent and claim is 1. In a leather-staking machine, in combination an oscillating roller-carrying arm having journaled at its free end' a grooved spreader-roll, provided with pinions, toothed segmental racks, engaging the said pinions, an intermittently-rotating staking-tool carrier provided with radially-actuating staking devices, and means substantially as described for oscillating said roller-carrying arm, and for intermittently rotating said carrier and intermittently moving its staking devices radially during the operation of the machine as and for the purpose set forth.
